The leader of Yemen’s Houthi Ansarullah movement says his country is fighting against forces led by the United States, Israel and Saudi Arabia as new evidence shows Saudis and the al-Qaeda terrorist group are colluding against the war-torn Arab country.

Abdul-Malik al-Houthi made the remarks while giving a speech in the country’s northwestern Sa’ada province on Monday.

While stressing that his nation has made many sacrifices and given many martyrs in their fight against the foreign invaders, he noted that Yemen is battling evil forces that seek to destroy the entire region.

Meanwhile, evidence has emerged showing military collusion between Saudi forces and al-Qaeda terrorists.

According to a report published by the state-run BBC on Monday, documentary maker Safa al-Ahmad found evidence of United Arab Emirates troops working alongside the al-Qaeda in the Arabian Peninsula (AQAP)-affiliate Ansar al-Sharia in Yemen’s southwestern province of Ta’izz.

During a visit to the province last year, Ahmad obtained footage of UAE troops supplying tactical information to Ansar al-Sharia militants.

Yemen has been under military attacks by Saudi Arabia since late March last year. The Saudi military strikes were launched in a failed effort to undermine the Ansarullah movement and bring Yemen's fugitive former president, Abd Rabbuh Mansur Hadi, back to power.

More than 8,300 people, among them 2,236 children, have been killed and 16,015 others injured since the start of the attacks. The strikes have also taken a heavy toll on the impoverished country’s facilities and infrastructure, destroying many hospitals, schools, and factories.
